An improved class of coning algorithms is presented to promote the maneuver performance of attitude updating of strapdown inertial navigation system. The improved coning algorithm is based on the match correction structure which can be designed through revising the previous half-compressed correction structure. The improved algorithm coefficient is designed from the existing compressed algorithm according to a given relationship. In order to analyze and evaluate algorithm performance under maneuver environments, two algorithm error models are defined. Compared with the classical compressed coning algorithm, the improved coning algorithm of the corresponding version has the same algorithm throughput and coning accuracy but has higher maneuver accuracy. Especially, the improved four-sample algorithm has about two times of maneuver accuracy compared with its classical compressed version.
